Abstract
A contactless power system for an automated data storage library having a plurality of storage shelves for storing data storage cartridges, at least one picker for accessing the data storage cartridges with respect to the storage shelves, and a transport system for guiding the picker(s) along at least one path with respect to the storage shelves. The contactless power system comprises a plurality of segmented coils arranged in parallel to the path(s), and in proximity to at least one induction receiver of the picker(s); and at least one power source supplying power to the segmented coils, for inductive transmission of power by the segmented coils to the induction receiver(s) of the picker(s). The power source(s) may switch the supplied power to selected segmented coils based on an indication of the position of the induction receiver(s) of the picker along the path.
